Installing the DHCP server

1. In Control Panel:Network, select Add Software.

2. Select TCP/IP components.

3. In the second window that is displayed, select the DHCP server item.

1. Go to the Network Administration Common Program Group and select DHCP Server.

2. Configure DHCP with a scope; a scope is a range of IP addresses available to be allocated to DHCP clients. For example, the scope could be the IP addresses 199.2.194.101 through 199.2.194.254.

   Defining a scope in Windows NT 4.x

   1. Click Start, Programs, Administrative Tools, DHCP Manager.

   2. Double-click the Local Machine option.

   3. Click Scope, Create.

   4. Enter the IP information to define the scope

   5. Open the Network Administration group.

   6. Double-click the DHCP Manager icon.

   7. Double-click the Local Machine icon.

   8. Click Scope, Create.

   9. Enter the IP information to define the scope

3. Define the lease. A lease is a pre-determined time that the printer will hold the IP address. When the lease time expires, the printer queries the DHCP server again for another IP address. It is recommended that you set the lease to Unlimited.

4. Define a name for the scope. You are prompted to activate the newly created scope. Answer Yes.

5. Restart the DHCP server.
   1. In Control Panel:Services, scroll down to DHCP Server.

   2. Click the Stop button, then click Start.

   3. Click the Close button.

6. Turn on the printer. The printer receives its IP address from the server. Print a Configuration Page to obtain the IP address (see The printer's Configuration Page).

7. Set up Print Manager to point to the printer's IP address. See Windows NT for more information.

8. Configure the printer's DHCP client software.

• On power up or reset, the printer sends a DHCP discover packet, indicating its Ethernet address and requesting an IP address.

• The DHCP server responds to the discover packet with a DHCP offer packet, which contains an IP address from within the assigned scope and the assigned lease.

• The printer examines the DHCP offer packet and decides whether to accept the lease. The printer sends a request packet, accepting the IP address and the lease.

  Note: There can be multiple DHCP servers on the same network, each defining its own scopes and leases. The printer selects the offer with the longest lease.

  ---

• The DHCP server sends an acknowledgment packet to the printer, which completes the transaction.
